Abstract: An interlocking panel system for top-down installation on an underlying structure including a plurality of panels, with an uphill course and a downhill course where each panel is generally rectangular, having an uphill edge and opposing downhill edge. An interlocking member is disposed along the uphill edge, and a receiving member adapted to receive the interlocking member and a joining flange are disposed along the downhill edge. A panel of the uphill course is affixed to an underlying structure via fasteners through the joining flange. The interlocking member of a panel of the downhill course is insertable into the receiving member of the uphill course, and the position of the panel of the downhill course is adjustable within the span of the receiving member.

Abstract: An interlocking panel system for top-down or bottom-up installation on an underlying structure including a plurality of panels, with an uphill course and a downhill course where each panel is generally rectangular, having an uphill edge and opposing downhill edge. An interlocking member is disposed along the uphill edge, and a receiving member adapted to receive the interlocking member and a joining flange are disposed along the downhill edge. A first panel is positioned on an underlying structure. In top-down installation, a clip is disposed along the downhill edge of the first panel and affixed to the underlying structure, and a second panel is engaged with the receiving member of the first panel. In bottom-up installation, the first panel is affixed to the underlying structure, and a second panel is engaged with the interlocking member of the first panel, and then affixed to the underlying structure.
